SPECIFICATION formingpart of Letters Patent No. 292,156. dated January 22, 18M. 1

-Application filed April 20,1883. (No model.)

To all whom it may concern.-

and JAMES J. GHRIsrIn, of the city of Camden,

county of Camden, and State of New Jersey,

have invented anlmproveinent in Glass-Molds,

of which the following is a specification.

Our in-ventionhas 'reference'to molding apparatus generally, but more particularly to glass-molds and it consists in detachably securing to the body of the mold the supporting I pin or handles,or both, and in many details of construction, all of which are fully set forthin the following specificatiom'and shownin the accompanyingdrawings,whichform part thereof.

Heretofore ithas been customary to support the molds from the standards by a bolt which is screwed or otherwise rigidly secured.t0 the body of the mold; but in time this bolt becomes broken, and leaves the broken part in the mold to be bored out and the hole tapped again to provide threads to secure a new screwthreaded bolt into place. The same construction is common with reference to the handles. The force required to keep the two parts of the mold closed is very great, owing to the large force exerted due to the expansion of the air within the mold during glass-blowing, and this force is transmitted to the handles and supporting -bolt, putting them under constant strain and ultimately causing them to break. \Vhen broken, it is practically impossible to insert new handles and bolts until the mold is cold, and hence involves a greatloss of time. p The object of our invention is to overcome the above objectionable features by providing suitable means to attach and detach said supporting bolts and handles, whereby the same may be readily replacedif broken, and without boring, tapping, or waiting for the mold to cool.

In the drawings, Figure 1 is a sectional elevation of our improved glass-molding appara tus on line y y. Fig. 2 is a sectional plan of same on line :0 m. Fig. 3 is-a perspective view of the supporting apparatus detached. Fig. 4 is a plan view of a glass-mold in which the two sections are closed and opened by handles. Fig. 5 is a sectional elevation of the present method of supporting the molds. Fig. 6 is a plan view, showing a modified form of con struction set out in Fig. 2; and Fig. 7 is aplan view of a modified form of support.

'A B are the two halves of the mold, and are is preferably closed at the top, as at d. L is the usual supporting-bracket, and is provided with aslot, L. Adovetailed block,

hinged on the bottom or back at C. One of the halves-say A-is provided w1th a lug, D, havinga dovetailed slot or groove, D, wh ch E, is clamped against said support by a bolt,

F, whose head f is countersunk in said block,-

and whose body passes through the slot L and Y clamped by a nut, G, over a washer, G. The slot LenablestheblockEtobeadjustedhighorlow; To prevent any possibility of the said block E turning,it may have lugs e e, which fit into the slot L of the bracket. The mold A B s supported by placing thepart A on the block E,

it entering the dovetailed slot D, and the two may be secured together by a set-screw,D ,'on1l other equivalent means, to prevent accidental separation. Now, should the bolt F wear out or become broken, a new one is readily replaced by simply taking block E out and inserting a new bolt in place of the broken one, and then securing the blockagain to bracket, when the mold may again be placed in position without any material delay. This construction is shown in Figs. 1 and 2, and enables us to use the old form of slotted standard; but by changing the form of slot in the standard we may dispense with the bolt, as shown in Figs. 6 and 7, as in the former we make the dovetailed block E double by putting on another and oppositely-arranged dovetail, H, which latter is adapted to fit adovetailed slot L, in the standard L, and made secure in any-desired position of height by a set-screw, M. If desired, as shown in Fig. 7, the dovetail block E and socket-piece or lug D may be dispensed with by simply securing the dovetail part H to the body A of the mold. Then there are no bolts tobecome broken and only one joint to make. If desired, the part A may have the dovetailed block cast or secured to it, and the adjustable block may be made with the dovetail slot or groove, this latter construction being some what simpler to finish; but they are simply equivalents. If. desired, these bolts F may be extended, as at N, Fig. 4,and be made to perform the function of handles. In this figure n are the heads of the handles or extended bolts, 0 the dovetailed blocks, and P the set-screws.

In place of making the handles as just described, they may be made as shown in Figs. 1

specified.

and 2, in which case the body of the mold has the dovetail block secured to it, and the handles or arms J, having heads j, are secured to the socket-pieces I, having dovetailed slots or grooves i, which fit over lugs H and are so cured in place by set-screws I.

In the drawings, N represents the handles, which are used to open and close the mold when they are operated by hand, and J the equivalent of the handles when the mold is opened by gravity and closed by foot-power operated through the lever K.

It is immaterial to our invention how the detailed construction is made-as, for instance, the usual T or L blocks may be substituted for the dovetailed blocks, as they are equivalents-for the invention comprehends, broadly, detachable handles and supporting bolts or blocks as applied to glass-molds or others of a similar nature.

\Ve are aware of the patents to Oakinan, No. 187,725, of 1877, Shinkle, No. 54,617, of 1866, and Granger, No. 254,687, of 1882, and claim nothing therein set forth or shown.

Having now described our invention, what we claim as new, and desire to seou re by Letters Patent, is-

1. A 1nold-body, in combination withablock I adapted to carry a replaceable handle, the said 1 block being detachabl y connected to said moldbody. substantially as and for the purpose 2. A mold-body provided with a dovetailed lug or its equivalent, in combination with a block having a dovetailed slot and adapted to fit upon said lug, and a bolt or handle supported and carried by said block, substantially as and for the purpose specified.

3. A mold-body and a supporting-standard, in combination with a dovetailed connection between said body and standard, substantially as and for the purpose specified.

4. A mold-body having a dovetailed groove and a supporting-standard alsohaving a clove tailed groove, in combination with a dovetailed connection between said body and standard, which consists of a double dovetailed block, substantially as and for the purpose specified.

5. A mold-bodyhaving a dovetailed groove and a supportin -staudard, in c mbination with a dovetailed block and means to secure said block to the standard, substantially as and for the purpose specified.

6. The combination of a moldbody, a supporting-block, and a standard, the said block being secured to the body bynieans of adovctailed connection, substantially as and for the purpose specified.

7. The combination of a mold-body, a supporting-block, a standard, and detachable handles, the said block being secured to the body by means of a dovetailed connection, substantially as and for the purpose specified.

In testimony of which invention we hereunto set our hands.
